OILJHEATER FOR ENGINES.

Specification of Letters Patent.

Patented Dec. 1, 1914.

Application filed March 18, 1914. Serial No. 825,644.

To all 'whom it may concern:

Be it known that I, THOMAS L. SCAFE, a citizen of the United States, residing at Kalkaska, in the county of Kalkaska, State of Michigan, have invented certain new and useful Improvements in Oil-Heaters for Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in oiling devices for engines, and particularly to heating devices for the oil to keep the oil in iiuid condition.

The principal object of the invention is to provide a simple and novel means for attachment to an explosive engine for heating the oil in the oil cup so that the same will feed properly.

Other objects and advantages will be apparent from the following description,

when taken in connection with the! accompanying drawings.

In the drawings: Figure l is a side eleva- .tion of a portion of an engine, showing the application lof my device. Fig. 2 is a top plan View thereof. Fig. 3 is a view similar to Fig. l, showing the position 'of the parts when it is desired to refill the oil cup. Fig.

f1 is a vertical longitudinal sectional view on the line 4-4 of Fig. 2. Y Referring particularly t the accompany- .ring drawings, lO represents a portion of an engine cylinder and ll the water tank mounted thereon, this tank feeding water to the water jacket of the cylinder. Mounted on one end of the cylinder is the usual oil cup 12.

The tank 11 is provided with a cover 13,

Copies of this patent may be obtained for and connected with this cover is a goosenecky pipe 14, said pipe extending down adjacent the rear end of the tank to a point slightly above the oil cup. Slidably mounted on the lower end of this pipe 14 is a tapering sleeve 15, the said sleeve having its larger end di rected downwardly and normally disposed over and around the oil cup.

The steam or hot Vapor from the water in the tank l1 passes through the pipe 14 to the cup 12. Thev heat from the steam or vapors will be imparted to the oil cup, and insure that the oil in the -cup will retain its fluid condition in very cold weather.

The upper end of the sleeve l fits snugly around the 'lower end of the pipe 14, but can be readily moved upwardly so as to 1incovcr the oil cup when it is desired to refill the cup.

From the foregoing it will be seen that I have provided a simple and cheap device for warming the oil in an oil cup of an engine so that the oil will retain its fluid state, especially in very cold weather.

What is claimed is An oil heating attachment for an engine,

in combination with a water tank, an oil cup therefor, of a cover for the tank, a hot vapor conduit connected to the cover and extending to a point over the oil cup, and a movable member on the conduit and covering the cup, said member being movable away from the cup to permit access thereto. i In testimony whereof, I affix mysignature, in the presence of two witnesses.
